A friend has a Kelley settling (blending) tank that he wants to sell.  It
is one of those with the paddles inside, which one can rig up to turn with
an electric motor, and the unit features a cone-shaped bottom w/water
reservoir and immersion heater.  I think it has been featured in the Kelley
catalog for many years.
 
This tank has not been used, or much anyway.  Anyone know what it might be
worth, or what Kelley is selling them for?
 
It doesn't appear to be of galvanized metal, but still it doesn't have the
luster of the Maxant or other stainless-type equipment, so maybe it isn't
stainless.
 
Thanks for any info...
